Happy dogs wag their tails to right, scared dogs to left

Tail wagging means a lot more to a dog than “I’m pleased to see you”, research has shown.

Most dog owners may not notice if their best friend’s tail wags more to the left or the right. But to another dog, the distinction makes a world of difference, scientists have found.

Put simply, a wag to the right signifies happiness, and a wag to the left fear.
